Unlocking new puzzles
Each level has a different number of stars you can get. "Practice" and "Easy" give you a maximum of four stars. "Normal" gives you a maximum of five stars. "Hard" has a maximum of six stars. After collecting twenty stars, new levels will open up (usually thirty new puzzles for every twenty stars).
Unlimited time
Press Start during game play to display the options menu. Although the touch screen is obscured, the timer stops. You can then look at the top screen to take as much time as desired to determine your next move. Resume game play, make your move, then pause game play again to repeat.
